Chapter 5 Introduction
|
||
|
|
======================
|
||
|
|
|
||
|
|
Welcome to Chapter 5 of the "Building an ORC-based JIT in LLVM" tutorial. This
|
||
|
|
chapter introduces the ORC RemoteJIT Client/Server APIs and shows how to use
|
||
|
|
them to build a JIT stack that will execute its code via a communications
|
||
|
|
channel with a different process. This can be a separate process on the same
|
||
|
|
machine, a process on a different machine, or even a process on a different
|
||
|
|
platform/architecture. The code builds on top of the lazy-AST-compiling JIT
|
||
|
|
stack from `Chapter 4 <BuildingAJIT3.html>`_.
|
||
|
|
|
||
|
|
**To be done -- this is going to be a long one:**
|
||
|
|
|
||
|
|
**(1) Introduce channels, RPC, RemoteJIT Client and Server APIs**
|
||
|
|
|
||
|
|
**(2) Describe the client code in greater detail. Discuss modifications of the
|
||
|
|
KaleidoscopeJIT class, and the REPL itself.**
|
||
|
|
|
||
|
|
**(3) Describe the server code.**
|
||
|
|
|
||
|
|
**(4) Describe how to run the demo.**

Full Code Listing
|
||
|
|
=================
|
||
|
|
|
||
|
|
Here is the complete code listing for our running example that JITs lazily from
|
||
|
|
Kaleidoscope ASTS. To build this example, use:
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
# Compile
|
||
|
|
clang++ -g toy.cpp `llvm-config --cxxflags --ldflags --system-libs --libs core orc native` -O3 -o toy
|
||
|
|
# Run
|
||
|
|
./toy
|
||
|
|
|
||
|
|
Here is the code for the modified KaleidoscopeJIT:
|
||
|
|
|
||
|
|
.. literalinclude:: ../../examples/Kaleidoscope/BuildingAJIT/Chapter5/KaleidoscopeJIT.h
|
||
|
|
:language: c++
|
||
|
|
|
||
|
|
And the code for the JIT server:
|
||
|
|
|
||
|
|
.. literalinclude:: ../../examples/Kaleidoscope/BuildingAJIT/Chapter5/Server/server.cpp
|
||
|
|
:language: c++
